Hello! All right?

Please, I need help with grok patterns.  
When I test with Dev Tools -\> Grok Debugger it works perfectly, but when I include it in the logstash filter it returns \_grokparsefailure.  
Is there a way to capture \_grokparsefailure response?  
Below is my configuration.  
Thanks for any help.

> input {  
> kafka {  
> bootstrap\_servers =\> "localhost:9092"  
> topics =\> "application"  
> tags =\> ["application"]  
> codec =\> json  
> }  
> }  
> filter {  
> if "application" in [tags] {  
> if [action][id] == "export\_send" {  
> grok {  
> patterns\_dir =\> ["/etc/logstash/patterns"]  
> match =\> { "newValue" =\> "%{NEWVALUE}" }  
> }  
> mutate {  
> add\_tag =\> ["YES\_Export"]  
> }  
> }  
> }  
> }  
> output {  
> if "application" in [tags] {  
> #stdout { codec =\> "rubydebug"}

When I run

```
input { generator { count => 1 lines => [ 'Output: Export (1)
Export name: test123
Export file format: salesforce
Amount requested: 1

Last balance: 43087128
Current balance: 43087127

Searched fields and terms:
    Identifiers: 04475444000129

' ] } }
filter {
    grok {
        match => {
            "message" => "Output: %{DATA:output}\\nExport name: %{DATA:export_name}\\nExport file format: %{DATA:export_file_format}\\nAmount requested: %{DATA:amount_requested}\\n\\nLast balance: %{DATA:last_balance}\\nCurrent balance: %{DATA:current_balance}\\n\\nSearched fields and terms: %{DATA:search}\\n\\tIdentifiers: %{DATA:identifiers}\\n%{GREEDYDATA}"
        }
    }
}
output { stdout { codec => rubydebug { metadata => false } } }

```

It works fine for me...

```
       "identifiers" => "04475444000129",
"export_file_format" => "salesforce",
       "export_name" => "test123",

```

etc. I suggest you read [this](https://discuss.elastic.co/t/help-needed-in-grok/213827/2).
